Every time I open in a new window, the new window is micro and I have to maximize it. This doesn't happen when I first open IE, only when I open any window from that into a new window. I've tried resizing the new one, and closing both. I've tried shift+clicking the x in the corner after resizing. I've even tried modifying the registry, but nothing seems to want to work.

Open a browser window. Click CTRL-N to open a new window. CLOSE the first window (key point). Resize the second window to the size you want it to be, and then do the SHIFT+CLICK on the X. Worked for me.
